Also a stabilized voltage is necessary.

Variable-frequency oscillator

A variable frequency oscillator (VFO) in electronics is an oscillator whose frequency can be tuned (i.e. varied) over some range. It is a necessary component in any tunable radio receiver or transmitter that works by the superheterodyne principle, and controls the frequency to which the apparatus is tuned.

Purpose

In a simple superhet radio receiver, the incoming radio frequency signal (at frequency ) from the antenna is mixed with the VFO output signal tuned to , producing an intermediate frequency (IF) signal that can be processed downstream to extract the modulated information. The IF signal frequency is chosen to be either the sum of the two frequencies at the mixer inputs (up-conversion), or more commonly, the difference frequency (down-conversion), , depending on the receiver design.

In addition to the desired IF signal and its unwanted image (the mixing product of opposite sign above), the mixer output will also contain the two original frequencies, and and various harmonic combinations of the input signals. These undesired signals are rejected by the IF filter. If a double balanced mixer is employed, the input signals appearing at the mixer outputs are greatly attenuated, reducing the required complexity of the IF filter.

Real Sociedad

Real Sociedad de Fútbol, S.A.D., more commonly referred to as Real Sociedad (pronounced:[reˈal soθjeˈðað]; Royal Society) or La Real, is a Spanish football club based in the city of San Sebastián, Basque Country, founded on 7 September 1909. Its home stadium is Anoeta, which seats 32,200 spectators. Real Sociedad won the La Liga title in 1980–81 and 1981–82, and last finished runners-up in 2002–03. La Real has also won the Copa del Rey twice, in 1909 and 1987. The club play the Basque derby against Athletic Bilbao. Real Sociedad were founder members of La Liga in 1928, and their longest spell in the top flight was for 40 seasons from 1967 to 2007.

Name and colours

The club's name means Royal Society of Football in Spanish. During the Second Spanish Republic (1931–1939), it was renamed "Donostia Club de Fútbol". The club is nicknamed in Basque as Erreala or the txuri-urdin ("white-blue" due to the colours of their kit). The colours stem from the flag of San Sebastian: a blue canton on a white field.
